2. Description of the Related Art

Generally, a bidet is a device installed at a toilet stool, and ejecting cleaning water or bidet water to clean user's genitals and rectal area after easing nature.

In this bidet, in order to give a smooth feeling to a user when water ejected from a cleaning nozzle and a bidet nozzle is in contact with a user's skin, the air is mixed with the ejected water.

A conventional bidet has employed a method of installing a separate component such as an air pump for mixing the air with the ejected water, or mixing the air using a pressure difference generated when cleaning water is ejected.

However, when the separate component such as the air pump is used, it is likely to generate abnormal noise while the cleaning water is ejected. In addition, the separate component may cause an increase in manufacturing cost and the size of the entire product.

Further, when the method of using a pressure difference during ejection of the cleaning water is used, since an air-mixing device is installed on front ends of the cleaning cylinder and the bidet cylinder, a large amount of foreign substances may be stuck to the front ends.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4.

Referring to FIGS. 1 to 4, an air-mixing nozzle for a bidet in accordance with the present invention includes a cleaning tip 3 and a bidet tip 8 having air-mixing means at each lower part of front ends of a cleaning cylinder 1 and a bidet cylinder 6, thereby mixing air using a pressure difference generated while cleaning water is ejected.

A cleaning water ejection port 2 for spraying cleaning water is formed at an upper end surface of the cleaning cylinder 1, and a plurality of bidet water ejection ports 7 for spraying bidet water are formed at an upper end surface of the bidet cylinder 6.

As shown in FIGS. 1 and 2, the cleaning tip 3 fastened to a lower end of the cleaning cylinder 1 has a cleaning water introduction port 4 formed at a center thereof. The cleaning water introduction port 4 is connected to an outlet of the cleaning cylinder 1 at its one side, and bent toward the cleaning water ejection port 2 in an “L” shape at the other side. The cleaning tip 3 further has an air introduction port 5 formed to be in communication with one side of the cleaning water introduction port 4 to introduce the external air using a pressure difference generated when the cleaning water ejected from the cleaning water introduction port 4 is discharged through the cleaning water ejection port 2.

As shown in FIGS. 1 and 2, since the cleaning tip 3 is inserted into a lower end of the cleaning cylinder 1 to be buried therein, foreign substances cannot stick to the cleaning tip 3.

Meanwhile, as shown in FIGS. 1 and 2, the bidet tip 8 fastened to a lower end of the bidet cylinder 6 has a water introduction port 9 connected to an outlet of the bidet cylinder 6. A plurality of ejection holes 10 are formed on the water introduction port 9. A plurality of air introduction ports 11 are formed at one side of the ejection holes 10 to be in communication with the ambient air such that the ambient air is introduced by a pressure difference generated when the bidet water ejected from the ejection holes 10 is discharged through the bidet water ejection ports 7.

The bidet tip 8 is also inserted into the lower end of the bidet cylinder 6 to be buried therein, thereby preventing foreign substances from being stuck thereto during operation.

In addition, as shown in FIG. 3, the cleaning cylinder 1 and the bidet cylinder 6 reciprocate in a state that they are accommodated in a nozzle guide 12. The cleaning cylinder 1 and the bidet cylinder 6 are driven by a drive member 20 composed of a single belt 23 and a gear 24 meshed with each other.

The drive member 20 is engaged with a predetermined length of belt 23 under a nozzle cap 22 engaged with a rear end of the cleaning cylinder 1 and the bidet cylinder 6. The belt 23 is meshed with the gear 24 rotated by a motor 21 to be rotated forward and backward, thereby reciprocating the cleaning cylinder 1 and the bidet cylinder 6.

The gear 24 has a rim 25 for preventing the belt 23 from slipping off, thereby ensuring stable operation of the belt 23.

Hereinafter, operation and effect of the air-mixing nozzle for a bidet of the present invention will be described.

When a cleaning or bidet function is performed, the motor 21 drives the gear 24 in one direction, and the gear 24 rotates the belt forward or backward, thereby reciprocating the cleaning cylinder 1 and the bidet cylinder 6.

When cleaning water is supplied into the cleaning cylinder 1, the cleaning water is introduced through the cleaning water introduction port 4 of the cleaning tip 3 to be sprayed to a user. At this time, the external air is introduced through the air introduction port 5 by a pressure difference generated when the cleaning water is ejected through the cleaning water ejection port 2 to be mixed with the cleaning water, thereby spraying the mixed air and cleaning water to the user.

In addition, when bidet water is supplied into the bidet cylinder 6, the bidet water is introduced through the water introduction port 9 to be sprayed to the user's genitals through the ejection holes 10 and the bidet water ejection ports 7. At this time, the external air is introduced through the air introduction port 11 by a pressure difference generated when the bidet water is ejected through the bidet water ejection ports 7 to be mixed with the bidet water, thereby spraying the mixed air and bidet water to the user.

As described above, the air-mixing nozzle for a bidet in accordance with the present invention is capable of mixing the air with the cleaning water and discharging them using a pressure difference generated when the cleaning water is ejected, and burying the cleaning tip 3 and the bidet tip 8 under the cleaning cylinder 1 and the bidet cylinder 6 to prevent contamination due to foreign substances.

As can be seen from the foregoing, an air-mixing nozzle for a bidet includes a cleaning tip and a bidet tip having air-mixing means disposed at front ends of a cleaning cylinder and a bidet cylinder each having a cleaning water ejection port and a bidet water ejection port to mix air using a pressure difference generated during ejection of the cleaning water; and a drive member having a belt and a gear meshed with each other to reciprocate the cleaning cylinder and the bidet cylinder. Therefore, it is possible to prevent foreign substances from being stuck to the bidet, and reduce the number of components by operating the cleaning cylinder and the bidet cylinder using the single belt driven by the gear, thereby improving productivity thereof.
